Intelligent peripheral system and call processing method thereof

1. In an IP (Intelligent Peripheral) system providing an IP information to a user through an advanced intelligent network system, said IP system comprising: means for storing and maintaining a special resource information for providing an intelligent network system to a user in accordance with a request of the user; and means for performing a protocol matching function and a call processing function between a service switching point (SSP) and a service control point (SCP) of the advanced intelligent network system, whereby said both means are separately installed for thereby implementing a direct connection to another intelligent network system through a common line signal network and easily expanding a resource channel.

2. In an IP (Intelligent Peripheral) system providing an IP information to a user through an advanced intelligent network system, said IP system comprising: a plurality of resource sub-systems storing and managing a special resource information provided to a user who uses the advanced intelligent network system; and a resource exchange sub-system which performs a protocol matching function and a call processing function between a service switching point (SSP) and a service control point (SCP) of the advanced intelligent network system, connects an internal time switch for driving a resource sub-system when being interfaced by a plurality of resource sub-systems and a LAN interface and receiving a message requesting a special resource driving from the SCP and providing to the user, sets a bearer channel with the SSP and sets a special resource channel with the resource sub-system.

3. The system of claim 2 , wherein said resource sub-system includes: a LAN interface forming a TCP/IP link with the resource exchange sub-system and implementing an interface with the LAN interface of the resource exchange sub-system; a special resource information storing unit for storing a special resource information for providing an intelligent network service to the user; and a trunk interface for matching a special resource channel set in the resource exchange sub-system for providing a user with a special resource information stored in the special resource information storing unit.

4. The system of claim 2 , wherein said resource exchange sub-system includes: a common line signal network platform for interfacing the IP system with a common line signal network; a first trunk interface for matching a bearer channel set between the SSP and the resource exchange sub-system; a second trunk interface for matching a special resource channel set between the resource sub-system and the resource exchange sub-system; a time switch for connecting a bearer channel transferred through the first trunk interface and a special resource channel transferred through the second trunk interface; a controller means for controlling the first and second trunk interfaces and the time switch; a LAN interface for interfacing with the resource sub-system for driving the special resource information stored in the resource sub-system in accordance with a special resource request of the intelligent network user; a protocol processor for processing a protocol between the SSP and the IP system which are the elements of the intelligent network system; a protocol processors for processing a protocol between the SCP and the IP system which are the elements of the intelligent network system; and a call processor for transmitting and receiving a signal message with the intelligent network system through the protocol processor and instructing an operation of hardware after judging the state of the hardware related with the controller means.

5. The system of claim 2 , wherein said network IP providing system is formed by expanding the capacities of the resource exchange sub-system and the trunk interfaces and the time switch of the resource sub-system and additionally connecting the resource sub-system to the resource exchange sub-system.

6. In a network IP (Intelligent Peripheral) providing system formed of a resource sub-system storing and managing a special resource information and a resource exchange sub-system performing a protocol matching function and a call processing function with a service switching point (SSP) and a service control point (SCP) of an advanced intelligent network system, a call processing method for the network IP providing system comprising: (a) receiving a request message for an intelligent network service from a user and transmitting an initial address message (IAM) to the resource exchange sub-system for a bearer channel connection between the SSP and the IP providing system at the SSP; (b) checking the capacity of the resource sub-system to provide a user with a special resource at the resource exchange sub-system which received the IAM; (c) transmitting an address receiving completed message (ACM) to the SSP and then requesting a special resource to the SCP when the resource sub-system is available as a result of the check of step (b); (d) selecting an available special channel among the special resource channels connected between the resource exchange sub-system and the resource sub-system in accordance with a special resource requested, requesting a connection to the time switch of the resource exchange sub-system for connecting the selected special resource channel and the bearer channel and transmitting an answer message (ANM) to the SSP; (e) driving the special resource of the resource sub-system connected by the special channel for receiving a special resource from the resource sub-system and transmitting a result of the special resource providing operation to the SCP at the resource exchange sub-system; and (f) maintaining a communication state so that a special resource is transmitted to the user through a special channel set between the resource sub-system and the resource exchange sub-system and a bearer channel set between the resource exchange sub-system and the service exchange.

7. The method of claim 6 , wherein said step (b) includes a step for analyzing the IAM received before the resource exchange sub-system checks the capacity of the resource sub-system and testing a continuity by connecting the time switch for a bearer channel loopback when a continuity test is requested.

8. The method of claim 6 , wherein in said step (e), the resource exchange sub-system drives a special resource of the resource sub-system and receives a special resource providing result from the resource sub-system using a LAN interface.

9. The method of claim 6 , wherein in said step (f), the communication state is stopped when there is not a message transmitted from the SCP to the resource sub-system for a predetermined time after the message is transmitted to the service controller.

10. The method of claim 6 , wherein in said step (f), the communication state is stopped when receiving an interface release request message from the service controller.
